1.0 INTRODUCTION Manufacturer’s data CARDIN ELETTRONICA SPA VIA RAFFAELLO 36 Tel. +39-0438-401818 31020 S. VENDEMIANO (TV) Fax.+39-0438-401831 ITALY Product marketing and commercial name S435 RADIO CONTROL (operating frequency: 433.92 MHz) consists of the following equipments: - miniaturized transmitter 2 channels (TX2) TRS435 200.0US - miniaturized transmitter 4 channels (TX4) TRS435 400.0US - wall mounted transmitter 4 channels (TX4M) TRS435 40M.0US - miniaturized transmitter 12 channels (TX12) TRS435 120.0US Note: the transmitter versions only differ from one and other by the number of functions (channels) which they are able to activate from a distance. The various containers differ from one and other by the number of buttons which depend on the model; it’s necessary remember that the four and twelve-channel transmitters use the same box but the twelve-channel transmitters has a selector to address the first, the second and the third channel bank. By looking at the wiring diagram it can be seen that all the transmitters feature the same radio frequency section and that only the encode section differs, due to the number of channel functions. - two-channel mini receiver (RXM2CH) RMS435 200.0US - one-channel mini receiver (RXM1CH) RMS435 100.0US - 120V radio programmer (RXPR) RPS435 000.0US Note1: the RF part in the 120V radio programmer is represented by the YRFIBR-433 module.

2.0 GENERAL DESCRIPTION - Radio control system model S435 consisting of one or more transmitters and one or more receivers; - Carrier frequency in the UHF waveband controlled by a SAW RESONATOR; - PCM type encoding signal transmitted in modulation bandwidth ASK; - Superetherodyne receiver, single conversion with local oscillator SAW, low rumor RF preamplifier and integrated RF-IF section; - Encoding and decoding device using a highly reliable 49 bit custom LSI, code transmission with complementary parity, automatic pre-chosen channel selection; - Highly reliable encoding system guaranteed by the use of dynamic codes. The code is changed for each encoding transmission through the use of an encoding algorithm which only the receiver is able to recognize and therefore decide whether or not the code transmitted corresponds to the original code. The code is generated for each channel in the transmitter using the random arbitrary method with 236 combinations. The generated code is memorized in the receiver via radio. The receiver is able to memorize 32 or 128 or 512 different codes. 2.1 USE AND APPLICATIONS The Radio control model S435 permits the remote activation of electrical and electronic appliances and has its best use in the following areas: • Automatic opening systems • Alarm systems and in all systems which require remote activation (without wires) using secret user codes in compliance with the local safety standards in force.
